SIGNALIN'G DEVICE.

Application filed August 14, 1911.

To all whom t may concern:

Be it known that I, RAY H. MANsoN, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful ,Improvements in Signaling Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to signaling devices and especially to warning signaling devices, such as are adapted to, be employed upon self propelled vehicles to give warning of the approach of such vehicles.

One of the objects of my invention is the production of a device of this character which will embody certain features and improvements` -I also aim to produce a device which can be easily manufactured by standard tools and which will be cheap and durable. I also aim to produce a device which will be protected from foreign matter and which can be readily and suitably mounted in a desired position on `any of the standard types of such vehicles.

I also aim to make the parts of my device easily assembled, inspected and readily removable for repairs and adjustments, where any one is necessary. In order that the contact. carrying member may be readily removed, independently of the armature, I mount the contact carrying member above the armature, providing suitable means to space the two apart. In order that they may be removed together, I connect them to the frame through the same means. I also mount one of the contacts upon a relatively long contact spring, so that the bendin may take place through considerable length thereof, since the flexing of a short spring through the range required will cause the spring to weaken and break in a short time.

Other lobjects of my invention and the ins vention itself, will be better understood by reference to the following detailed descrip'- ton when taken in connection with the .accompanying illustration, showing one specific embodiment of the invention, while lthe scope will be more particularly pointed out in the appended claims.

Fig. 2 is a detail.

Referring now to the drawing and to the embodiment of the invention there shown, at l is shown a casing part, which forms one of the walls of the chamber 2. The part 1 is perforated at 3 for the passage outward of sound waves, which are created inside the chamber. A resonator 4 may be mounted in this opening for the purpose of directing and amplifying the sound waves. This member may be omitted if desired. A sound producing member, such as a vibratile diaphragm 5 is mounted within the chamber. The edge of the part 1 is preferably turned over, as shown at 6. A part 7 forms another wall of the chamber 2. In the form shown this part -consists of a cylindrically shaped cup, which is preferably punched from a single piece of sheet metal. The edges of the cup are turned outward at 9, forming an annular flange 8, which is preferably, substantiallyv at right angles to the walls of the cup 7 The sound producing member 5, a vibratile diaphragm, in the form shown, is clamped between this annular flange and the front 1, by some suitable fastening means, such as screws 10. The rear of the cup 7 is perforated, as shown at 11 and an anvil 12, which may be mounted upon the diaphragm, extends through this perforation to the outside of the cup. Means for operating the diaphragm, such as an electromagnet 13 are mounted within the chamber 2, being as shown in the form illustrated, best mounted upon the bottom, of the cup on the inside thereof. Studs 14 and 15 are mounted upon the bottom 100 of the cup on the outside thereof. The stud 14 carries the vibratile armature 16 of the electromagnet 13, which is so positioned that when the'armature is attracted it strikes the anvil 12, thereby causing the sound producing member to emit sound waves. The stud 15 carries a contact 17, which is here shown as adjustable and which coperates with the contact 18 carried by spring member `19, mounted preferablyy upon the stud 14. These two contacts constitute an 4electric switch, which controls the electromagnety 13, the said switch being opened whenth'e magnet' is energized and closed when-denergized. By this particular form of structure, I provide a protecting Acasing for the magnets which are housed away in a safe place, whereas, the contacts and the armature, which from time to tune ojo.

need attention and adjustment are mounted in a place Where they can be easily reached and attended to. A casing 20, preferably a 'hollow casing,Which may be substantially -mounted upon the part 7 serves to protect the armature and the contacts, and at the same time may be readily removed for the purpose of inspection and adjustment.

This particular form of structure is cheap to make, can be readily made With standard forms of tools and with standard shop practice; it is durable, convenient and oders suitable protection to the parts, and, at the same time is handsome and neat in appearance.

lnasmuch'as instruments of this type are manufactured as a standard output, it is greatly desired that they should be so made that it Will be convenient to mount them in any position upon a vehicle. Some owners desire to mount them upon a side wall and some upon the end Wall, or some other position. To meet this demand, l have provided a particular form of bracket, which when combined with my instrument results in an article which will meet such demand. The casing? is perforated at 30 and a screw 31 is mounted therein with its head 32 inside the casing. The turn table piece 33 is mounted outside the casing, being keyed to `the head of the screu7 by key 34. A. nut 35 holds the tlirn table piece in position upon the casing.

A bracket 36, preferably an angular bracket, is here shown as an 'sliaped bracket. This bracket is provided at one end with a Wing, preferably a flat Wing 3?, which is arranged to be far-itened to a flat surface; for example, it is perforated at 38 .for screws, bolts or other fastening means, with which it may be attached to fiat surfaces, though, of course, i" may construct this Wing of such shape as is best suitable tor mounting. The other end of the bracket carries the mounting l0, which is here shown as a cylindrical mounting for the purpose of pivoting the signaling device therein. l prefer to provide this mounting with a Web 41 near the center thereof and substantially perpendicular to an element ot the Walls of the mount- This 'web is perforated at 42 for the passage of the screws 8i. When mounted upon this bracket, the instrument may be lockedin position by suitable locking means, such as a nut a3, which is fastened on the end of the screw. lt `will readily be seen that this nut i3 may he loosened and the signaling device may be rotated upon the mounting to a desired position and locked there, it being possible to fasten the Wing 37 either to the front or side of the caf, or to an angularly directed piece and the signaling de vice then rotated until the resonator is tor-s imanes Wardly directed, in which position the signaling device may be locked in the mounting.

lt will be plain to those skilled in the art that numerous and extensive departures from the form and details of this embodiment of the invention may be made Without departing from the spirit Aot the invention, the same being shown herein solely for the purpose of illustrating one embodiment of the invention.
